The present paper fills a gap in the knowledge of the largest marsh beetles in the Neotropics. Argelodes gen. nov., Solierodes gen. nov. and Mucronotus gen. nov. are described from Southern South America. Argelodes and Solierodes are monotypic, contain Argelodes magnificus sp. nov. and Solierodes rousseli (Solier, 1849) comb. nov., while Mucronotus contains five species: Mucronotus velutinus (Solier, 1849) comb. nov., M. schwabei (Pic, 1938) comb. nov., and three newly described ones—M. enigmaticus sp. nov., M. patagonicus sp. nov., and M. valdivianus sp. nov. Affinities of newly described genera with Australian taxa are briefly discussed. Pronotal modifications in marsh beetles are illustrated and discussed.

The systematics of the Family Carditidae is currently poorly elucidated. This paper reviews the Eocene to Pleistocene carditids from Patagonia and Entre Ríos Province (Argentina). Twelve species are described and illustrated and the presence of the genera Cyclocardia Conrad, Pleuromeris Conrad, Scalaricardita Sacco, Fasciculicardia Maxwell and Purpurocardia Maxwell in southern South America is discussed. The genus Scalaricardita is documented for the first time in South America. Two new genera, Darwinicardia gen. nov. and Kolmeris n. gen. are proposed for the species ‘Venericardia’ patagonica (Sowerby) and ‘V.’ tehuelchana (Ihering), respectively, and one new species, Cyclocardia dalek sp. nov., is described.

Forcipomyia (Pterobosca) incubans Macfie (1937) (Diptera: Ceratopogonidae) is recorded here for the first time for Brazil. Females were collected in the Brazilian Neotropical Savanna parasitizing the wings of Erythrodiplax juliana Ris (1911), Erythrodiplax aff. anomala Brauer (1865) and Erythemis credula Hagen (1861), all Libellulidae dragonflies. A map of potential distribution of this species in the New World is also provided. The results suggest that its distribution may range from southern South America to Mexico, with higher densities in the Brazilian and Colombian Tropical Rain Forests.

AbstractAspiciliopsis macrophthalma, Placopsis fusciduloides, P. gelidioides and P. tararuana are reported for the first time from southern South America. New records for 13 species of Placopsis in southern South America are reported, and a revised key to 22 species of Placopsis and A. macrophthalma in the region is given.
